Preparation method of iprolol hydrochloride

The invention provides a preparation method of iprolol hydrochloride. The method comprises the following steps: reacting thionyl chloride and methanol to prepare methyl chloride. Methyl p-hydroxyphenylpropionic acid methyl ester is prepared by substitution reaction of p-hydroxyphenylpropionic acid and methyl chlorite. The etherification reaction of methyl hydroxy phenylpropionic acid methyl ester and epichlorohydrin is prepared to obtain 3 - [4 - (2, 3 - epoxypropoxy] phenylpropionic acid methyl ester. 3 - [4 - (2, 3 - Epoxypropoxy] phenylpropionic acid methyl ester and isopropylamine undergo amination reaction to prepare the ilomolol. Diaprolol hydrochloride and hydrochlorination of hydrogen chloride to obtain ilomolol hydrochlorideThe method has the advantages of easily available raw materials, low cost and simple preparation method. The target product has high yield, high purity and market competitiveness.

Pd(II)-catalyzed intermolecular arylation of unactivated C(sp 3)-H bonds with aryl bromides enabled by 8-aminoquinoline auxiliary

An example of using readily available, less reactive aryl bromides as arylating reagents in the Pd(II)-catalyzed intermolecular arylation of unactivated C(sp3)-H bonds is described. This reaction was promoted by a crucial 8-aminoquinolinyl directing group and a K2CO3 base, enabling regiospecific installation of an aryl scaffold at the β-position of carboxamides. A mechanistic study by DFT calculations reveals a C(sp3)-H activation-led pathway featuring the oxidative addition as the highest energy transition state.

Hitting a soft drug with a hard nucleophile: Preparation of esmolol's metabolite by treatment with bis(tributyltin) oxide

A facile method for the production of esmolol's metabolite in high purity is described. Bis(tributyltin) oxide is used to disrupt esmolol's ester linkage, and hydrolysis is completed by addition of water, which also allows the inorganic side products to be conveniently extracted into ether. Evaporation of the aqueous phase and trituration with ethyl acetate provides the carboxylic acid-amine internal salt as a white, free-flowing powder. Taylor & Francis Group, LLC.
